- NEW MEANS AND SYSTEM OF HEATING.

Application filed February 14, 1918.

To all whom it may concern:

Be it known that I, AARON TERRY, a citizen of the United States ofAmerica residing in Springfield, in the county of Humpden and State ofMassachusetts. have invented New Means and Systems of Heating,

of which the following is a specification, reference being had to theaccompanying drawings and letters of reference marked thereon.

It is a well known fact that the heating systems now in use are noteconomical and that many experts claim that from 75 to 90 per cent. ofthe heat units are wasted and that as a general rule not exceeding 5 percent. of the heat units are actually utilized for heating purposes.

In the systems now in use a large perccnb age of the heat units are lostbecause of the fact that the heat is largely taken up in heating the.conduits and heavy radiators and because of the fact that the heatedgases escape through the chimney without first .giving up the heatcarried by them.

The objects of my invention are to provide a means whereby a very muchlarger percentage of the heat units may be utilized for heating'purposes than has heretofore been attained, and a means or systemwherein the'waste heretofore had is largely avoided;

I accomplish the objects of my invention by the construction hereinshown.

In the accompanying drawings illustrating one embodiment of my inventionand in which like characters 0 reference indicate like parts,

Fig. 8 is a detached view of a section of the heating drum.

()ne of the great problems in heating a dwelling or other huilding isthe (lifliculty of utilizing thc hcat :urtually generated by the heatingmeans and of conducting the heat units to the dcsircd point.

For illustration in a steam heating plant it becomes necessary to hcatthe water in the boiler, which must result in heating the boiler itselfand all appliances connected therewith, thus wasting a large amount ofthe heat units at the outset. Thc whole circulating system must then hehcutcd in order to conduct the steam at a sufiicientlv high tcmpcraturoto the room to he heated. It then becomes necessary to supply sullicient heat to heat a radiator, thus again taking up the heat unitsbefore they reach a point. where the room begins to receive th benefitof the heating-system. It is a wel known fact that a large volume of theheal units are carried away in smoke and other products of combustion sothat but a cour paratively small pcrcentage of the heat generated by theheating means is in fact utilized for heating purposes:

Inorder to overcome this condition and provide a means whereby the heatactually generated at the source may be readily absorbed, given oii' andconducmd to the de sired point I avoid the use of heavy, thick materialand'provide a construction wherein the heat units may be rapid] athsradcarried to the point desired e orev the ten. perature is materiallyreduced.

The first step to accomplish the result to be attained comprises theemployment of one or more heating drums each constructed by preference,as at present advised. as shown in Figs. 4, 5, -(i and 7. This drumcomprises an outer shell 1, formed of thin material, preferably sheetcopper or brass and by prcfcrcuce having its surface con rugated.\Vithiu the outer shell I arrange an inner shell 2 of like constructionand ar range the some substantially as shown in Figs. 4, (i and 7. Thebottom of the shell 1 is open, while the bottom of the shell 2 isclosed. Both shells are open at the top. Between the outer and innershells of th heating drum I prefer to arrange a basket like structuresimilar to that shownin Fig. 2.

Referri now to Fig. 4, heat is applied to the lower open ended portion 4and it will be readily seen that the heated air will pass upwardlybetween the shells l and 2 and become rapidly absorbed by these shells,and as the shells have large corrugated radiating surfaces, with theircorrugations arranged to ballie the heated air so that in its passageupward between said shells it will be deflected back and forth from oneto the other, they will generate intense heat and give it off in greatvolume. If, now, an arrangement be made so that the air currents willflow up between these two shells, the air will become heated and if theair so heated be quickly conducted through proper conduits to the roomsor places to be heated, a very much larger percentage of the heat unitswill be utilized for heating purposes than has heretofore been foundpossible.

The employment of a heat radiating member, such as the basket-likestructure 3 shown in Fig. 2, arranged between the outer and inner shellsof the drum serves to break up and further heat the air currents andbring all particles in contact with a heated surface, thus insuring thethorough heating of all the air passing between the shells of the drum.

In Fig. l I show a construction wherein the heat absorbed by the innershell will be permitted to flow upwardly and because of the employmentof a dish shaped deflecting plate 5 will be deflected dowmvardly and beagain thrown in contact with the heating drum, and will then passupwardly in its outward travel in substantially close contact with theupper portion of the inner shell and thus be further heated andconducted to the desired point, so that in the construction shown inFig. 4 the heat units absorbed by the air in contact with both the innerand outer shell may be utilized.

In Fig. (l I illustrate two drums opening at the top into a conduit 22,and an arrangement whereby air is allowed to enter the inncr'and bottomportions of the inner shells 2 through an approximately vertical conduit6 having horizontal branches 23 which turn downwardly and open above theclosed bottoms of said inner shells. The air thus introduced into theinner shells 2 is projected or descends onto the bottoms of said shells,and then rises in contact with the sides of said shells, and to this endthe outlet terminals of the' branches 23 are surrounded with annulardeflectors 33. T he intake of the conduit 6 must be below the level ofthe open bottoms of the shells 1, in an inclosure to which particularreference will subsequently be made, with the discharge ends of saidconduit or of its branches 23 just above the closed bottoms of theshells 2, as previously observed. Thus the passage of air into theshells 2 is insured, and the air is discharged at the points where it issubjected to the most intense heat.

Suitable dampers 7 and 8 are provided for the heating drums in theconduit 22 for regulating the flow of air from the heatin drums, and forcutting off either of sum drums. r V

The drums in this view, Fig. 6, are heated by means of gas-burners 51 ona T 52 at the inner end of a pipe 53 which receives its supply from anoutside pipe 54.

In order to facilitate the flow of the heated air I prefer to arrange afan 9 in the conduit 22 preferablfy driven by an electrio motor 10,which n will operate to force the air u wardly to the desired point.

In Fig. 6 I s row an arrangement of water tanks 11 designed to moistenthe heated air on its passage.

In Fig. 7 I illustrate a construction wherein coal coke or other likefuel may be conveniently employed and with this arrangement I prefer toemploy a reservoir 12 arranged at an elevation above the fire box 13with a conduit 14 extending between the two and I provide a fan 15,driven by a motor 16, the fan being arranged in a conduit 17 extendingto the ash box 18, by the employment of which fan a forced draft may behad and a more complete combustion attained. In this figure I alsoillustrate the employment of a hot air fan 9, driven by a motor 10. Theconduits 19 and 20 lead to a chimney and thus dispose of the products ofcombustion, but as the smoke and other heated products of combustionpass upwardly between the corrugated outer and inner shells of the drumsthe heat units will be absorbed so. that the smoke and gases 'willpassiout through the chimney, after having given off substantially allof the heat units carried by them. The heat unitsgiven oil' by the outersurface of the outer shell 1 of the drum will pass upwardly and throughthe conduits 21 connected with the on la of the furnace and are mixedwith the cat units which pass upwardly from the interior of the drumthelatter being forced upwardly by the an as before described.

Air, as before described, is admitted to III mamas means ma be employedto heat the drum, it simply eing necessary to rovide means which willfurnish heat to t e lower open end portion of the outer shell 1 of thedrum, or in other words to provide means for furnishing heated air topass upwardly between the outer and inner shells and, as before stated,it is also desirable to provide means in many instances for the flow ofair to the interior portion of the inner shell of the drum so that theheat units to be given off by the shells may be utilized for heatingpurposes. It will therefore readily be seen that the employment of gas,kerosene, electricity or other means for heating may be employedwith mydevice. I

Electricity might be employed as a heat-' ing means, and one way inwhich it could be applied would be through the medium of .a resistancecoil or similar element located'at the base of the drum or drums.

I do not limit myself to any particular means for furnishing heat andapplying the same to the drum or drums.

It will also be seen that the arrangement of conduits, dampers, fans anddeflecting devices may also be arranged and com structed differing indetail and location from that shown by me without departing from thespirit of my invention, and I therefore do not limit myself to theconstruction shown, but refer to the same'as one embodiment of myinvention.

The cupola in which the conduits 21 are located is mounted at the top ofan inclosing structure 25 having at the top deflector members 24 whichdirect the'heat waves from the drum or drums below to said cupola. Thisstructure or inclosure is made with the end in view of conducting theheat generated by the inclosed drum or drums to the conduits 2'1 with aslittle loss as possible. The aforesaid drum ordrums are supported withinthe inclosure 25, in the presentainstance, by being suspended from alight cross bar 30 having its ends seated in brackets 31 on oppositesides of said inclosure." i

The urpose of the inclosure 25 is to conserve. t e heat radiated fromthe outer'sh'ell or shells 1 and thus to insure'the utilization ofpractically all of. the heat generated by the drum or drums for heatingthe rooms to which it is conveyed by way of the conduits 21. Theconstruction of the apparatus as a whole is such that little or no heatis given oil from the inclosure 25'into'the space surf roumling thesame, but; is conveyed away,

l t rough the top of said inclosure:

The ofllfie of the fan 9 is threefold era-st,

the action of the fan draws the air into the. shell or shells 2-throughtheconduitfi or 6"; second, said action sucks the air out-of the top ofsaid shell orshells, and out of the top ofthe shells 1 in the Fig. 6construction;

1 taken from -be'lowthe heating and comparative y fresh and livelyclosed at the bottom,

and third, said action forces the air Mpwardly toward the conduits 21.This is an important and .valuable feature of the invention. y

Air from the outside is an plied to the inclosing structure 25 throng aconduit 50, Figs. 1,6, and 7, which opens into the back side of saidstructure. i

The air supplied to the interior of the shell or shells 2, in eitherexample herein shown, being of the temperature of the air in theinclosure 25, from which it is taken, is in consequence more uniform orevenin tfimperature and much better adapted for t e urp'oselforwhich itis used than would? 4 outside. And the uniformity or evenness isenhanced by reason of thefact that the air is oint or points, thus beincool without being cold,

as is needed for the supply to the shell or shells 2. Having thereforedescribed my invention whatI claim .as new and desireto secure byLetters Patent is:-'
